Logical Volume Manager (LVM) (ตัวจัดการโวลุ่มเชิงตรรกะ (LVM)) Tool
Logical Volume Manager (LVM) is a storage device management tool that provides flexible disk space allocation by abstracting physical storage into logical volumes, allowing dynamic resizing and improved storage management.
Expertise Level
Level 1
Basic
1. Understands the basic concepts of LVM such as physical volumes, volume groups, and logical volumes.
2. Can perform simple LVM commands like creating and listing physical volumes.
3. Recognizes the benefits of using LVM over standard partitioning.
Level 2
Intermediate
1. Can create, resize, and remove logical volumes and volume groups.
2. Performs backups and restores LVM metadata safely.
3. Manages physical storage devices to optimize volume usage and performance.
Level 3
Advanced
1. Designs complex storage architectures using LVM including snapshots and thin provisioning.
2. Troubleshoots and recovers from LVM-related failures and data inconsistencies.
3. Integrates LVM with other storage technologies for scalable and resilient solutions.
